Constructor Detail

HibernateCacheStore

public HibernateCacheStore(String entityName)

Constructor which accepts an entityName

Parameters:

entityName - the Hibernate entity (the fully-qualified class name)

HibernateCacheStore

public HibernateCacheStore(String sEntityName,
                           String sResource)

Constructor which accepts an entityName and a hibernate configuration resource. The current implementation instantiates a SessionFactory per instance (implying one instance per CacheStore-backed NamedCache).

Parameters:

sEntityName - Hibernate entity (i.e. the HQL table name)

sResource - Hibernate config classpath resource (e.g. hibernate.cfg.xml)

HibernateCacheStore

public HibernateCacheStore(String sEntityName,
                           File configurationFile)

Constructor which accepts an entityName and a hibernate configuration resource. The current implementation instantiates a SessionFactory per instance (implying one instance per CacheStore-backed NamedCache).

Parameters:

sEntityName - Hibernate entity (i.e. the HQL table name)

configurationFile - Hibernate config file (e.g. hibernate.cfg.xml)

Method Detail

store

public void store(Object key,
                  Object value)

Store a Hibernate entity given an id (key) and entity (value)

The entity must have an identifier attribute, and it must be either null (undefined) or equal to the cache key.

Specified by:

store in interface CacheStore

Parameters:

key - the cache key; specifically, the entity id

value - the cache value; specifically, the entity

storeAll

public void storeAll(Map entries)

Store a collection of Hibernate entities given a Map of ids (keys) and entities (values)

Specified by:

storeAll in interface CacheStore

Parameters:

entries - a mapping of ids (keys) to entities (values)

erase

public void erase(Object key)

Erase a Hibernate entity given an id (key)

Specified by:

erase in interface CacheStore

Parameters:

key - the cache key; specifically, the entity id

eraseAll

public void eraseAll(Collection keys)

Erase a set of Hibernate entities given an collection of ids (keys)

Specified by:

eraseAll in interface CacheStore

Parameters:

keys - the cache keys; specifically, the entity ids
